The APS12 Advanced Smart Grid Power System is one of the most advanced and complete power systems of the market. It is not a simulator but a real system.
The APS12 is able to show any electric phenomenon that are present in real power systems, such as short circuits, over currents, over voltages, over frequencies, reverse power, generator runaway, black out, etc.
All power systems are formed by three fundamental parts:
- Generation System.
- Transmission/Distribution System.
- Load System.
- Generation System:
Power generation is the point where all power systems born, where transmission lines emerge up to distribution lines and finally, to give electrical service to the final consumer. It is necessary a great quantity of control variables for a power system reliable, safe and optimal because of these variables depend the electrical energy quality. The most important 217 control variables allow the user to interact with a sophisticated, real and intelligent generation system, which is able to respond automatically against energy demand, it is able to protect automatically against short circuits, with light indicators and alarms that will allow us to understand at all time the generation system state.
- Transmission/Distribution System:
After power generation, transmission and distribution systems are required to give power to the final consumer. These systems are highways of aluminum and steel which transport great quantities of power up to strategic points of the country and even other countries. In the transmission systems is very important to know variables such as transported energy, length transmission lines, capacitive effect, energy losses produced along kilometers and kilometers, etc. Besides, in a transmission line system is not enough a conventional protection system. For these systems are required distance protection relays able to detect changes in the line impedances and to sense undetectable anomalies for other conventional protection relays.
Distribution substations adapt the transmission lines voltage levels up to lower voltage levels for energy distribution. On this point take importance the distribution transformer with voltage regulator, which are able to compensate the transmission liens drop voltages.
The transmission/distribution power system of APS12 allows to study all these control variables and much more. The most important 111 control variables allow the user to interact with the transmission/distribution system.
- Load System:
One the energy is transported, this has to be carried to the consumption points through distribution lines. Final consumer provokes changes in the power balance of the system from generation up to distribution. On this way, all machinery of the system (generation, transmission and distribution) works in real time in order to the electrical parameters remain constants in the consumption points.
In the consumption points is very important to ensure the electrical energy quality through reactive energy compensation devices. Besides, on this point are essential the feeders management protection relays, which are installed in strategic points of the distribution lines giving to the grid the required reliability, safety and efficiency. These protection relays monitor electrical variables such as frequency, voltage, current, power factor, etc. In order to protect the grid.
The load system of APS12 allows to study all there control variables and much more. The most important 158 control variables allow the user to interact with the load system.
